If I have a BS in computers and Masters in MIS, how many years do i need to study to become a dentist?
I have a BS in computer science and Masters degree in Management information system. I am interested in pursuing dentistry but since i am in my 40s i am not sure how many years I would need to be in school before I can start my practice.

Dental school is different altogether. Expect to spend many years to become a dentist or only several months if you want to be a hygienist.
